MATTHEW EUINTON, or WE T uP oN, MASSACHUSETTS.

COMBINED LEVEL, SQUARE, AND BEVEL.

EBPECIPICATION forming part of Letters Patent No. 315,264, dated April'7, 1885.

Application filed September 12, 1884. (No model) To wZZ whom it mayconcern.-

Be it known that I, MATTHEW EUINTON, of West Upton, in the county ofWorcester and State of Massachusetts, have invented a new and usefulCombined Measuring, Leveling, Plumbing, Squaring, and BevelingInstrument for Carpenters Use, and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings',forming a part of thisspecification, and in which Figure 1 represents a plan or top edge viewof my aforesaid improved carpenters tool or instrument. Fig. 2represents a side view of the same, and Fig. 3 a side edge view of theinstrument, looking in the direction indicated by the arrow in Fig. 2.

To enable those skilled in the art to which my invention appertains tomake and use the same, I will proceed to describe it more in In thedrawings, the part marked A represents an ordinary spirit-level. It alsoin this instance constitutes one side of a square, the other side beingformed by the longer part B, which may be marked off into inches andfractions of an inch for measuring, in a similar manner to an ordinarycarpenters square or rule, as is indicated in the drawings. The part Bmay be made so as to measure two feet, instead of one, as shown, or anyother desired length. It may be fastened to the spirit-level A in anyconvenient and well-known manner.

In this instance I form a central longitudinal slot in one end of thelevel, insert the end of the part B in the same at right angles to eachother, and then fasten the two parts in position by means of the dowelsor pins 12. By thus formingasquare of the level A and part B having thestraight sides A B at right angles to each other, as above described,the instrument, as will be seen, may be used for plumbing as well asleveling, measuring, and squaring purposes, by obtaining the level inthe usual way and plumbing.

from the vertical side B.

The part marked 0 represents an adjustable segment-gage for gaginginclined angles-as, for instance, the angle of atapering chimney orsimilar inclinations required to be gaged in practice. Said gage 0 maybe inserted in one or theother of the correspondin l -sha ed slots ormoves 0 a made crossg 5 P g wise in the surface of the part B, or whennot in use placed in a slot or groove, 0 madelongitudinally in the partB. In all of the afore said positions it is held from falling out of theslotin which it is placed by means of a thumbscrew, (1, or latch d, asshown in the drawings. In order to fully illustrate the application ofsaid gage, I have represented it in Fig.2

in all of the positions before described. The outer or convex edges ofthe gage are marked 011 into inches and fractions of inches, the same asan ordinary rule. I have represented both sides as being marked, forconvenience in reading, the distance itis moved out or in when used oneither end of the part B; but,if preferred, they may be marked,as shown,only on one side, or to read in reverse directions from each end. Thedistances from the outer convex sides of the slot 0 to the corner e,(see Fig. 2,) and from the same point on the slot 0 to the corner f ofthe square, are just one foot, and the circles forming said slots arestruck from said points as centers. Therefore, by moving the gage Gin orout to or from the straight side B any inclination to a foot may readilybe obtained between the points of contact, either inward oroutward, or,in other words, between the ends of the gage O and points e f, as isshown by dotted lines 9 in Fig. 2; and when thus adjusted and fastenedas before described the instrument may be used not only for thelast-named purpose, but also with equal facility for the various otherpurposes hereinbefore described.

The gage 0 may be varied inlength to Having described my said invention,what I claim therein as new and novel, and desire to secure by LettersPatent, is-- 1. The combination of the rule B, provided and holdingscrews or iatches d d, constructed With the segment slots or grooves 0 ccflwith and arranged substantially as shown and de- 10 the segment partor gage O and its holding scribed, for the purposes stated. screws orlatches d d, substantially as and for 5 the purpose Set forth MATTHEWEUINTON.
